FAQ

Does ESG investing mean sacrificing returns?

Research suggests ESG investing doesn't necessarily sacrifice returns and may offer risk-management benefits.

How do I know if a fund is truly ESG?

Look at the actual holdings, not just the marketing. Review the fund's ESG methodology and exclusion criteria.
